Everyone needs a little bit of "me time" now and again, but too much solitude can make us lonely and irritable and put us in a not-quite-right state of mind. According to recent medical research reported by Discovery News, similar stir-craziness has been observed in bacteria that are sequestered... Read More
Aker University Hospital is a dingy place to heal. The floors are streaked and scratched. A light layer of dust coats the blood pressure monitors. A faint stench of urine and bleach wafts from a pile of soiled bedsheets dropped in a corner.
Look closer, however, at a microscopic level, and th... Read More
An international group of researchers has sequenced and characterized the genome of a cavity-causing bacterial species called Bifidobacterium dentium, identifying key features that have helped the bug become a tooth decay specialist.
The team, which includes collaborators from Europe, the UK,... Read More
A new study reports a surge in drug-resistant strains of a dangerous type of bacteria in US hospitals: Acinetobacter strikes patients in Intensive Care Units (ICUs) and others and often causes severe pneumonias or bloodstream infection, some of which are now resistant to imipenem, an antibiotic ...

University of Delaware researchers have uncovered a novel means of conquest employed by the common reed, Phragmites australis, which ranks as one of the world's most invasive plants.
The invasive strain, which hails from Eurasia, overtakes its "native" cousin, which has lived in North America... Read More

My new paper in Nature (using a Creative Commons license so anyone has access to it) on a "Phylogeny Driven Genomic Encyclopedia of Bacteria and Archaea." In this paper we describe our project to fill in the gaps in the tree of life (of bacteria and archaea" with genome sequences and thus corre... Read More
At least 111 million doses of vaccine against pandemic H1N1 influenza are now available and least 60 million people have already been immunized, according to the Centers for Disease Control and Prevention. "The vaccine supply is getting better and better, and surveys are showing that the initial... Read More
Antibiotic resistance in the natural environment is rising despite tighter controls over our use of antibiotics in medicine and agriculture, Newcastle University scientists have found.
Bacterial DNA extracted from soil samples collected between 1940 and 2008 has revealed a rise in background ... Read More
Scientists have identified a strain of antibiotic-resistant tuberculosis that thrives in the presence of rifampin, a front-line drug in the treatment of tuberculosis. The bacterium was identified in a patient in China and is described in a study by researchers at the Johns Hopkins Bloomberg Scho... Read More
A report published in the new journal Science Translational Medicine has made an interesting discovery concerning the relationship between sugar intake and the balance of intestinal flora. Researchers have discovered that a diet high in sugar and fat substantially alters the bacterial compositio... Read More
In a novel study, researchers from University of Gothenburg, Sweden have found that the cellulose produced by bacteria could be used to develop artificial blood vessels in the future.
They say that bacterial cellulose carries a lower risk of blood clots than the synthetic materials currently ... Read More
Staphylococcus aureus causes far more serious infections than previously realised, with more than 3,000 Swedes affected every year, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.
To date there have been no reliable data on just how common this often dea... Read More
Researchers from the La Jolla Institute for Allergy & Immunology will take aim at several of the world's most dangerous infectious diseases — tuberculosis, malaria and dengue virus — in a five-year, $18.8 million federally funded set of projects seeking to make new inroads toward vaccines agains...

On Dec. 1, 2009, the United States Department of Energy notified the University of Chicago Medical Center that it had full approval to “commence research operations” at the newly constructed Howard T. Ricketts Laboratory, operated by the Medical Center to study the organisms that cause infectiou... Read More
Researchers at Albert Einstein College of Medicine of Yeshiva University have developed a new approach for treating and healing skin abscesses caused by bacteria resistant to most antibiotics. The study appears in the journal PLoS One.
Abscesses are deep skin infections that often resist anti... Read More
The often feared and sometimes deadly infections caused by MRSA -- methicillin-resistant Staphylococcus aureus -- are now moving out of hospitals and emerging as an even more virulent strain in community settings and on athletic teams, and raising new concerns about antibiotic resistance.
